# A Bag Contains Cards Which Are Numbered from 2 to 90. a Card is Drawn at Random from the Bag. Find the Probability that It Bears A Number Which is a Perfect Square - Mathematics

Sum

A bag contains cards which are numbered from 2 to 90. A card is drawn at random from the bag. Find the probability that it bears a number which is a perfect square

#### Solution

Total no. of possible outcomes = 89 {2, 3, 4, …., 90}

E ⟶ event of getting a no. which is perfect square

No. favourable outcomes = 8 {4, 9, 16, 25, 36, 49, 64, 81}

P(E) ="No.of favorable outcomes"/"Total no.of possible outcomes"

P(E) =8/89
